SPINDLE.

SPECIFICATION forming part of Letters Patent No. 255,074, dated March 14, 1882.

l Application tiled July 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. CARROLL, of Worcester, Worcester county, State of Massachusetts, have invented an Improvement in Spindles for Ring-Spinning Frames, ot' which the following description, in connection with the accompanying drawings, is a specification.

My invention in spindles has i'or its object to reduce thejar of the spindle when ruiming,-

1o and entirely obviate any evil effects resulting from the band-pull, which is exerted in but one direction.

In my improved apparatus the lower end of the spindle is held and supported laterally by means of ablock or washer of india-rubber,

leather, or equivalentyielding medium or elastic material, fitted closely within a cavity at the upper end ot the whirl, the latter being sustained during its rotation by a short pintle 2o below the whirl, and either connected therewith or inserted therein loosely, as may be desired. The spindle has a bearing in a bolster which is so supported in its shell or case that the bearing may rock freely and permit the spindle to move into true central position.

Figure l represents in elevation and partial vertical section a spindle constructed and supported in accordance with Inyinvention; Fig. 2, a cross-sectionthereof on the dotted line x 3o m, Fig. l; and Fig. 3, a modification showing` the whirl fitted to turn on a short xed stud.

The spindle a is extended through a bolsterbearing, b, made elliptical externally in the direction of its length, and placed in the case c. The case will he held in a bolsterrail, as usual, and owing to the shape ofthe bolster :it is free to rock with the spindle in the said case. The lower end of the spindle has afoot or collar, a2, above which is placed a block or 4o ring of indiarubber, leather; or other suitable elastic material, d, iitted snugly and closely to the said spindle, and also within the sleeve e, extended upward from the whirl f, which receives the usual band which is to drive the spindle.

Ifdesired,the footorcollar azmay be notched to engage a projection at the upper end of the pintle g, with which, as in Fig. l, thewhirlfis secured, the said pintle enteringa foot-step or bearing, h., in the rail i. The sleeve e of the 5o whirl is screw-threaded, and receives the cap j, which retains the yielding washer or block d in the cup. The hole at the top of the cap, through which the spindle is extended, is of somewhat greater diameter than the spindle, to allow it to move a little laterally without touching the cap. The usual band ot` the spi nning-frame, in the groove of the Whirl f, will rotate it, together with the yielding packing tilted snugly to it, and will revolve the spindle 6o in unison with it; but the spindle, it is obvious, will in no manner be affected or strained out ot' perpendicular position by reason of the bandpull, for the whirl is not carried by the spindle, or in any way rigidly secured thereto.

If the spindleioot is notched to t a projection, 2, moving with the whirl, such connection will assist in rotating the spindle; but such connection is not absolutely necessary.

Instead of xing the pintle g to the whirl, 7o as in Fig. 1, I may bore the whirl to receive a pintle, n, fixed to the rail t' and extended upward as in Fig. 2.

Removing the whirl entirely from the spindle and causing it to revolve with or on a stud below it, while the spindle is supported by a yielding packing, is productive of numerous advantages, among which are avoidance of the band-pull on the spindle and the ease with which the spindle finds its true centerof rota- 8c tion withoutjar.

The bolster-bearing b is shown as grooved in the direction of its length. lo receive the wick o, and is perforated at p for the passage ot' oil from the wick to thespindle. 85

I-elaim- The whirl, its cup, and a pintle, and yielding washer or block fitted closely therein and to the spindle, combined with the independent spindle, bolster-case, and yielding or rock- 9o ing bolster therein, substantially as shown.

In testimony whereofI-have signed my name to this specication in the presence of two subscribing witnesses.

WILLIAM T. CARROLL. Witnesses:
